[1] Attosecond pulse shaping at fermi fel p / P. K. Maroju, C. Grazioli, M. D. Fraia et al. // ABSTRACTS BOOKLET and Summary of The 5th International Symposium on Intense Short Wavelenght Processes in Atoms and Molecules (ISWAMP). — Paris, France, 2019. — P. OC–01–OC–01. Free-Electron Lasers (FELs), which can generate radiation in extreme ultraviolet and Xray range along with unprecedented intensities, opened up opportunities for investigation of the valence and core electron dynamics. The temporal coherence and the high intensities have made possible the single-shot diffraction [1] imaging of non-crystalline samples. However, until recently the longitudinal coherence was not demonstrated which is essential for coherent control experiments [2]. In this work, we present the first demonstration of generation and characterisation of Attosecond Pulse Trains (APTs) at the seeded FEL FERMI exploiting the ability to produce multiple phase locked harmonics. We also demonstrate the ability to manipulate the amplitude and phase of the generated APTs independently.
